From Dazayuan to Xiangjiang, I Use E-Commerce to Push the Times

In 1958 in Beijing's Forty-Nine City, in a large courtyard next to Nanluogu Lane, a thin young man opened his eyes amid hunger and cold. His name is Lin Yue - or more accurately, the owner of this body is called Lin Yue, and he, a junior student from the 21st century, a "full-level social cow" who dominates the campus club, is currently lying on this leaky earth kang, his stomach is so hungry that his chest is pressed against his back, and he has only a handful of bones in his body. Along with him, there is a cheat system called "Blue Star E-commerce (Fusion Version)". This system does not sell martial arts secrets, does not increase the level of immortality, it only does one thing - e-commerce transactions across time and space.
